Thresholds from the Attribute Threshold sectors and then waits for the host to transfer the 512
bytes of Attribute Thresholds information from the device.
SMART ENABLE/DISABLE ATTRIBUTE AUTOSAVE (Code D2h)
This subcommand enables and disables the attribute auto save feature of the device. The
SMART Enable/Disable Attribute Autosave subcommand allows the device to automatically save
its updated Attribute Values to the Attribute Data Sector at the timing of the first transition to Active
idle mode and
after 15 minutes after the last saving of Attribute Values. This subcommand causes the auto save
feature to be disabled. The state of the Attribute Autosave feature—either enabled or disabled—
will be preserved by the device across the power cycle.
- A value of 00h—written by the host into the device's Sector Count Register before issuing
the SMART Enable/Disable Attribute Autosave subcommand—will cause this feature to be
disabled. Disabling this feature does not preclude the device from saving Attribute Values
to the Attribute Data sectors during some other normal operation such as during a power-up
or a power-down.
- A value of F1h—written by the host into the device's Sector Count Register before issuing
the SMART Enable/Disable Attribute Autosave subcommand—will cause this feature to be
enabled- Any other nonzero value written by the host into this register before issuing the
SMART Enable/Disable Attribute Autosave subcommand will not change the current
Autosave status.
The SMART Disable Operations subcommand disables the auto save feature along with the
device's SMART operations. Upon the receipt of the subcommand from the host, the device
asserts BSY, enables or disables the Autosave feature, clears BSY, and asserts INTRQ.
SMART SAVE ATTRIBUTE VALUES (Code D3h)
This subcommand causes the device to immediately save any updated Attribute Values to the
device's Attribute Data sector regardless of the state of the Attribute Autosave feature. Upon
receipt of the SMART Save Attribute Values subcommand from the host, the device asserts BSY,
writes any updated
Attribute Values to the Attribute Data sector, clears BSY, and asserts INTRQ.
SMART EXECUTE OFF-LINE IMMEDIATE (Code D4h)
This subcommand causes the device to immediately initiate the set of activities that collect
Attribute data in an offline mode (off-line routine) or execute a self-test routine in either captive or
off-line mode. The LBA Low register shall be set to specify the operation to be executed.
